"This is totally erroneous. We did not send these letters," said spokesman for the Election's Office Travis Abercrombie.

The department was flooded with calls from voters statewide who received a letter from their election supervisor indicating they're ineligible to vote. To do so could result in arrest.

"We were contacted by people, three so far in Hillsborough, who got letters that were suspicious in nature indicating these people were not citizens and that they were ineligible to vote," said Abercrombie.

The letters, postmarked from Washington state with no return address, were delivered in Seminole, Hernando, Collier, and Hillsborough counties. The feds immediately alerted all 67 counties in Florida to these fraudulent letters being sent to white Republican supervoters like Travis Horn.

"In all of my years as a voter, and involved with the Republican Party since I got out of the Army in 1994, I've never seen any voter fraud scheme that was as sophisticated as this. I mean, this is a scary scam they're running," said Horn.

The letters look legit, complete with the election supervisor's name, a patriotic logo, and a formal body of copy. 10 News showed the letter to workers in downtown Tampa for reaction and most thought the letter looked real.

The scheme is so nefarious, Florida Governor Rick Scott said, "We have zero tolerance and [it is being dealt with.]"
